When there is no key operation, balance information is processed and, when a condition not satisfying below + or -20g with respect a zero point continues for 10sec in a weighing mode, a message display flag is erected and the net wt. or a price is calculated to be displayed. A specific message is preliminarily stored in RAM 18. By this constitution, an article name display device 13 is utilized to make it possible to perform message display to a customer.

Then the interruption of the TXX is accepted only when all CPUs are through with their initialization, and the cycle heads of interruptions applied to the CPU 1 - CPU n are made even. Then all CPUs are started at one time after these CPUs are prepared. Thus the control cycles of all CPUs are made even.
